CORN-SHELLER.

Specification of Letters Patent No. 15,502, dated August 12, 1856.

To all whom ii' 'may concern.'

Be it known that I, CALVIN ADAMS, of Oak Hill, in the county of Greene and State of New York, have invented a new and Improved Corn-Sheller; and I do hereby de- Clare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, Figure l being a top view of said machine; Fig. 2, a section in the line a: of Figs. 1 and 3; Fig. 3, a section in the line y y of Fig. 2, and Fig. 4t a side view of a detached portion of the machine.

Similar letters indicate like parts in all the figures.

The cylinder of my improved corn-Sheller is composed of a series of independent toothed wheels a, a, combined with each other and with the angular-shaped main shaft A, in the following manner, viz: Each of the toothed-wheels ai, has a central aperture of such a size that it can be slipped freely upon the shaft A, and from the base of the teeth b, b, on one side of each toothed wheel there laterally projects a thin flanch c, a distance about equal to the thickness of the wheel, so that should said wheels by themselves be slipped one after the other upon the shaft A, spaces would be left between the series of teeth Z2, o, of each wheel, about equal to the width of said teeth. But before slipping the said toothed wheels upon their driving shaft I place upon the flanch of each wheel a partially toothed ring e, whose thickness is a little less than the width of said flanch. Each of said partially toothed rings e, has an eye-hole projection e, from one side of its periphery, which receives a retaining rod g, whose ends are made fast in apertures in the sides of the machine. The teeth j", f, of the rings e, e, radiate from about one half the circumference of the rings, commencing at the bottom and extending upward nearly to the top of their peripheries and being of the curved shape represented in the drawings. The shelling cylinder of my corn-Sheller it will therefore be perceived is armed with annular series of rotating teeth which alternate with a semi-annular series of stationary teeth. The said shelling cylinder of my improved corn-sheller is combined with a toothed rack composed of curved independent segments 7L, 7L, which are of the shape represented in the drawings. The teeth j, y',

of the segments e, e, are of the same width as the teeth I), b, of the rotating wheels a., a, and the said segments are arranged and retained in such positions that their teeth lare exactly opposite the teeth of the rotating wheels a, a. The said toothed segments h, 71., are connected with and supported by the transverse shafts Z, and B, as shown in Fig. 2. The said shaft Z, passes through oblong openings in the rearward projections 7c, lc, on the upper portion of the after sides of said segments, and the shaft B, passes through angular openings r, r, near the lower extremity of said segments, which are inclosed within t-he projections s, s. From the upper ends of the segments h, 7L, down to a short dist-ance below their rearward projections 7c, 7c, a thin ianch z', projects laterally from one side of each of the segments, as represented in Fig. 3. The said segmentfianches z', z', correspond in width with the Hanches c, c, which project from the toothed wheels a, a, and they consequently serve to keep the upper ends of the segments at such a distance from each other that they will not exert any binding influence upon the toothed rings e, e, while they also serve to keep the teeth of said segments exactly opposite the teeth of the rotating wheels a, a. The lower ends of the toothed segments z, 7L, are kept at the proper distance from each other by means of the short flanches or lugs p, 2'), one of which lugs projects laterally from one side of each segment, as shown in Figs. 2 and 3.

A horizontal bar m, whose ends work in grooves or guiding recesses in the sides of the corn Sheller, bears against the outer edges of the series of toothed segments lz., L, immediately below the projections lala, on said segments. The said bar mi, has rearward projections m', m', from each end, which projections are connected to a spring plate n, and the said spring plate n, is acted upon by a set screw 0, which works in a screw aperture in the rear end of the corn Sheller.

The angular opening 1', at the lower ex'- tremity of each toothed segment 71 is of such a size that it will permit the lower ends of the segments to rise to about the distance of half an inch from the extremities of the teeth of the rotating cylinder a, and the oblong openings in the segment projections le, c, are of such a length that the segments can give back to adapt their positions to the Alternating the annular roWs of rotating teeth of the shelling cylinder With stationary toothed rings, When the said shelling cylinder is combined With a rack composed of a series of self adjusting toothed segments, substantially in the manner herein set forth.
